FIFO in the chain to go LOW after a word has been read from the last FIFO is
the sum of the delays for each individual FIFO:
(N – 1)*(3*transfer clock) + 2 TWCLK
where N is the number of FIFOs in the expansion and TWCLK is the WCLK
period. Note that extra cycles should be added for the possibility that the
tSKEW1specificationisnotmetbetweenRCLKandtransferclock,orWCLKand
transfer clock, for the
IR flag.
The Transfer Clock line should be tied to either WCLK or RCLK,
whichever is faster. Both these actions result in data moving, as quickly as
possible, to the end of the chain and free locations to the beginning of the
chain.
